Ted Marsh, President of Marsh Racing, has been involved in professional racing for more than 35 years. The team has been very successful in NASCAR’s Featherlite Modified, Nationwide and Busch Grand National Series. On the road racing side, Marsh has been very successful in the Speed World Challenge GT Series, Grand Am Rolex GT series and NARRA.

Marsh Racing is a Connecticut based team currently competing in the NASCAR K&N Pro Series East. Formerly the team had competed in the NASCAR Busch, Nationwide and Modified series. The team is owned by Ted Marsh, a longtime Chevrolet team sporting the No. 31 with backing from Whelen Engineering. His former IMSA (International Motor Sports Association) drivers included Boris Said and Eric Curran; his former NASCAR drivers included veterans Steve Park, Andy Santerre, Dave Blaney, Ted Christopher, Todd Bodine, Johnny Benson, Tim Fedewa, Richard Childress Racing development driver Peyton Sellers, and Turner Motorsports standout James Buescher.  His most current driver, David Garbo Jr., is driving the team's Chevy SS in the 2015 season.

After many years in the Modified series dating back to 1967, Marsh Racing began competing in the Busch Series in 1983 with Ken Bouchard.The team entered races in Daytona, Rockingham, Darlington, Charlotte and Dover with support from M J Sullivan Chevrolet, a long time Marsh Racing Supporter.

In the mid 90’s, Ted Christopher started driving for Marsh Racing in the Busch North Series. The team added Whelen Engineering support in 1996 and went on to win multiple times at New Hampshire as well as Watkins Glen and Limerock Park.

For the 2000 season, Marsh Racing selected Steve Park as the team's driver and Whelen Engineering returned as the sponsor for a limited schedule with the newly renumbered #31 car in the national Busch Grand National Series. Park put the car in the field nine of the fourteen events the team attempted and gave the team a new top finish in the national series when he placed 6th at Richmond. He also gave the team three top ten starts and a best start of second at Richmond.

Park returned to the team in 2001 and made all seven on the team's attempts. He posted five top ten finishes including a fourth at Bristol. The team almost managed two top ten starts with a third place start at New Hampshire. In September 2001, while Steve Park was driving the car, he suffered a severe concussion and was unable to race. Andy Santerre took over the car for the final three races of the limited schedule for the season, however mechanical failures plagued each race.

For the 2002 season David Green, Tim Fedewa, and Dave Blaney drove the car at different points throughout the season. The team posted a best finish of 14th at Bristol with Fedewa driving. Unfortunately, the team suffered through four mechanical failures and three crashes throughout the season. Dave Blaney returned to the car for the 2003 season after working with the team late in the 2002 season.

The team also switched to Ford from Chevrolet for the 2003 season, with Blaney bringing support from Jasper Motorsports, the team he was driving for in Winston Cup at the time. Competing in ten events, he managed six top 15 finishes with a best finish of 9th at Richmond. His best start during the season was a 4th at Chicagoland.

In 2004, the team again started the year with Dave Blaney driving the #31 Whelen Engineering Ford, however after three races he was replaced with Todd Bodine. Bodine would give the car its best finish of the season when he finished 5th at Homestead-Miami.

Dave Blaney returned the #31 team in 2005 and brought support from Richard Childress Racing as they switched back to Chevrolet. The team's best finish of the season came at Dover when Blaney finished 12th and the best start of the season came at Richmond where the team started 7th.

For the 2006 season, it was announced that Steve Park would return to Marsh Racing and drive the car in ten races. Peyton Sellers made his Busch Series debut at New Hampshire with the #31 team and made another start at Memphis Motorsports Park.

In early 2008, Turner Motorsports Development driver James Buescher was driving at select races. James qualified 18th, and finished 20th at the US Cellular 200 in Newton, Iowa. Then came the Camping World East Series 125 At The Glen at Watkins Glen, NY. They qualified 20th, but due to engine trouble, had to withdraw from the event.

Meanwhile, the team was actively involved with Sonny Whelen, driving a Viper in the Viper Days Series, which later became NARRA. The team, with Sonny driving, won Rookie of the Year and 2 Driver's Championships by the end of 2006. Sonny had decided to attempt running the SCCA World Challenge events and quickly changed to Corvettes. 

In 2007, a 2 car team was started with Sonny Whelen and Eric Curran as drivers. The team competed in World Challenge for several years, winning multiple races, and then switched to Grand Am (The Grand American Series) in 2010. The team added Boris Said as the second driver for Eric Curran after Sonny Whelen stepped down due to an illness. The team won the final race of the Grand Am Series at Limerock Park before Grand Am became the Tudor Championship Series in 2013.

In 2014, the team is still intact, except this year, the Corvettes gave way to Daytona Prototypes. The team is currently campaigning the Corvette Daytona Prototypes in all Tudor events.  

In 2015, the team moved to the K&N Pro Series East.  The team raced the entire 2015 schedule with David Garbo Jr. as the primary driver.  The team started the 2016 season at New Smyrna with a 7th place finish by Ryan Preece.
